Understanding Pulse Width Modulation - Part 1

[octaviansorescu]

Greetings Mr. Stuzman! Today I bought a PWM module to test the Egr at Golf MK6 Tdi. I also bought two DC sources, one for the digital transducer that handles the position of the Egr valve. And one for the 12v motor that drives the Egr valve. You made me better understand how the PWM principle works. Thanks!

Thank you for ur time and expertise. ...I personally like when people explain things with a white board.. The biggest room in my house is the room for improvement. Every bit of information i can get is awesome. thank you again

You are too good Terry, that was totally enjoyable. I'm sitting here going more, more. Thanks for your time and effort.

Excellent video. Best I've ever had it explained to me. Also thanks to Eric O for sending us viewers in your direction. Will now be a steady follower of your videos thanks

Thank you! Finally I understand how voltage change by changing the duty cycle and not the frequency! Good job.

[SouthMainAuto]

Great job Terry! Also is a great example of how the pulse pulse-width can change but the frequency stays the same very good jobs

[j.jonahjameson]

Such a fantastic job of breaking down a complicated subject. Thank you

[bodgitandleggitgarage]

fantastic video mate great explanation I don't think many people realise exactly how much information you can get from a square wave especially when you put techniques and equations In to it

[DENicholsAutoBravado]

The duty cycle calculation surprised me a little but it made perfect sense. Since frequency remains the same, I had never considered counting the on and off together for the denominator as I figured it was a set value for a given circuit. It's a solid way to teach itnof course.

Very nice one, Terry. thank you for this easy to understand lesson.

[OneAuto]

Thats a great video Terry. Like you say we see PWM all the time in the automotive game and that was an easy to understand explanation. Well done sir!

[EXOVCDS]

Great explanation of PWM! Formulas / equations make a lot more sense to me now... compared to when I was in school!

[ozzstars_cars]

Good explanation on PWM. I haven't seen that much algebra in 25 years! lol The future video on the IAC will be a good practical example on how it all comes cycle, frequency and pulse width. Looking forward to it. Take care Terry

[obediahgarcia]

Thanks for the awesome fundamental illustration and examples stutzman!

[zardow]

Great videos sir, waiting for the next video. Thumbs up.

[normansmith]

Great job Terry ! Explained to where even I can understand !

[Badgertronix]

excellent explanation Terry. Thank you for the education.

[haywardsautomotive]

Great explanation Terry. I love math but now I'm older I like selecting it and BAM done or SORTED :D Great video Terry!

[spelunkerd]

Every time I turn around I find a PWM circuit, so there must be some reason for it to be so popular in automotive circuits. It seems to be a way of translating digital information into an analog output (or vice versa). I'm looking forward to your IAC description.

Wait, let me get my note book. Okay, go! And now were at the end. That equals...Outstanding!
